You realize your point is even stupider now, right?
The first thing to remember here is GSP making reference to his ability to make LW. That is the first step here. Now with that in context:
If we were talking about Khabib who had already ended or was ending his career facing GSP, then a one off at WW could be entertained, and we can inspect that with a microscope. But you're saying that a guy who IS CURRENTLY the 155 champ called for the guy who said he could try to make 155 is some kind of duck because the champ didn't suggest it for 170 (ya know, the division the champ doesn't have a belt in). Because that makes sense, right?
